Distributing Applications and Data
The topics that follow are intended to help you plan the overall
configuration of the workgroup, in terms of what pieces of the workflow
reside and run on what systems. This section will make better sense if
you have already read “Choosing a File-Sharing Model” on page 56; you
will notice that the discussion is biased towards the “Client-Server
Model” on page 59.

HP-UX File-Sharing Model (V.4)
HP-UX introduced a new file-system layout at 10.0. The new layout is
based on the AT&T SVR4 and OSF/1 file systems and is intended to
provide benefits such as:
• the separation of operating system software from application
software
• a foundation for file-sharing models such as “NFS Diskless Model” on
page 57 and “Client-Server Model” on page 59
• consistency with other UNIX vendors
See the HP-UX 10.0 File System Layout White Paper on
http://docs.hp.com for more information.
How Does this Help You Share Files?
The new layout is cleaner and more logical than 9.x, it is essential for
NFS Diskless (see “NFS Diskless Model” on page 57), and it should make
interoperating with other vendors’ UNIX systems simpler.
It doesn’t change the mechanics of configuring NFS mounts, but it does
make managing them easier in one important respect: the segregation of
non-“system” applications under /opt, and the changes applications
such as Netscape have made to comply, mean that the server can now
